The vert-ical shaft 89 carries two trips 92 .of :whichis abovethe rockshafts 56, '57, 58 and 59, as clearly shown by Fig. 1 of-the vertical planes 'so that. oney will open valves and the other will close said valves after they have remained open the The operation of the separator is as follows. The belt wheel 68 is being revolved and is revolving shafts 48', 49 and 89 and conveyers 83 and 84 are-in operation.` Cam wheel 90, trips 92 and 93,' and the bag shaking cams (50 and 51 and' tlief two not shown) are revolvng.- The dust laden air is'entering compartm'ent 8 and passing into the interiors of the bags, passin "through the bags (except escribed) leaving the dust and particles in the bags and escaping past the open 'valves in the short pipes into comand thence through conduit 15 place iofdischarge: The Vbags when the air are quiet, that to say, they are 'notshaken when their parto the a' partieula'r -controlling the passage of the air from the to levers 107, 108, 109

ticular valves -are open because the lever' for bag-is Velevated when the valve compartment in which that bag is located 1s openfEa'ch Vvalve is open the greater part of thetimc and its particular 'bag is quiet and'iltering the air during that period. To-

keep the bags clean'so that. their meshes will nct become 'clogged they arev shaken periodically. vThe trip 93 contacts with the lower end of oneof the trip arms and rotates the rockshaft to which it is secured until the throw-over weight passes the vertical. The welght falls and closes its valve. -After the y valve is closed the free end of the lever belonging tothev group of that valve and bag falls into the recess 91 in thecam wheel 90..v :The lii'ik-carriedby-that lever is lowered, the yoke inthe link Ashaking cam and the-bag is Shaken by an -up anddown movement, the' annular weight has come into reach of the 27 jerking the bag down when the cam part 34 of the/yoke slips from the ca'min a manner which will be readily understood. The bag is shaken until 4the cam wheel 90 in its revolution haselevatedthe free end of the lever from the recess 91 and so elevated .the

link ad yoke that the cam is without effect on the cam part 34 of the yoke. Soon thereafter ,thevtrip 92 contacts with the upper end of the 'trip arm and rotates the rock shaft in the opposite direction until the throwover weight passes the vertical. The weight then falls' and opensthe Valve permitting the filtering operation to resume.

The construction and mode of operation of the 'modiiiedform of construction illustrated by Fig. 4 of the drawings is very .similar to that of the preferred form already described.v In this construction 'the casing 94 is provided with the horizontal partitions 95` and 96 dividing the interior 'of the casing into three compartment-S97, 98 and 99 and compartment 99 is in open communication with the atmosphere, through aperture 100. Four bags, only two of 'which are shown 101 and 102 are located in compartment 99 and they are secured to imperforate heads supported by rodsV 103 from yokes 104 provided with cam parts 105. The yokes are reciprocatable in links 106 secured and 110 and the links are retained within guides 111 the same as in the preferred form of construction al-l ready described. `The operation of spur gear 112, worm 113, worm wheel 114, cam wheel 115, band pulley 116, pinion 117, shafts 118 and. 119, cams 120' and 121, screw conveyer 122. and scraping conveyer 123 is the same asV that of the corresponding, parts in the preferred'form of construction already described at length and that description does not require repetition. The short pipes, of which only' two 5124 and 125 are shown, are..placed below the bags and are provided with valves 126, 127, 128 and 129 on rock shafts to which are secured trip-arms 130, 131, 132 and 133. Esch rock shaft is also provided with a throw-over weight 1311. lThe vertical shaft 135 is provided with two trips 136 and 137 to cooperate with the trip-arms 130, 131, 132 and 133 in the manner already described.

The vaircurrent exhaust from the fan (not end of the lever belonging to the group of that particular bag drops intothe recess 139 1n the top of cem Wheel 115 lowering the link and' yoke so that .the bag is 'shakenv While its is closed.

What 1 claim is:

1. )Qn e separator, shaking mechanism for a bag comprising a yoke, provided with al l@am part, a cem for reciprocating said yoke, a link serving as a guide for the yoke While it is reciprocated and adapted to elevate the vyoke so that it will not be reciprocated by 'the ca m, and means to intermittently elevate said link and yoke.

2. In a' separator, shaking mechanism for a'bag comprising a yokefprovided -with a cam part, a cam for reciprocating said yoke, a link serving as a guide for the yoke While it is reciprocated and adapted to elevate the yoke so that it will not be reciprocated by the cam, a lever connected to said link, and :t camwheel with a recess in its upper surface-adapted to 'be revolved'under the end of said Jever.
